Karthik Kambatla commented on YARN-1776: ---------------------------------------- The approach looks reasonable, and changes (except FSRMStateStore) look good to me. I would prefer someone more familiar with FSRMStateStore also take a look. > renewDelegationToken should survive RM failover > ----------------------------------------------- > > Key: YARN-1776 > URL: https://issues.apache.org/jira/browse/YARN-1776 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Zhijie Shen > Assignee: Zhijie Shen > Attachments: YARN-1776.1.patch, YARN-1776.2.patch, YARN-1776.3.patch > > > When a delegation token is renewed, two RMStateStore operations: 1) removing > the old DT, and 2) storing the new DT will happen.
